A new report says smog can contribute to
premature death. Rebecca Williams reports:
Ozone is a main ingredient in smog – it comes from cars and smokestacks and
other sources.
The National Academies of Science report says ozone can send people to the
hospital, and even lead to earlier death. That’s because ozone can damage
your lungs and make it harder to breathe. It can be especially bad for
kids, older people, and people with lung diseases.
Dan Greenbaum is the president of the Health Effects Institute. He worked
on the report.
“It just reinforces the risks of exposure to ozone are there, they’re
significant and people really should be paying attention to alerts when
there are high ozone days.”
Ozone alerts mean even healthy people should avoid working or exercising
outdoors during the day.
The EPA recently tightened the ozone standards. But the agency’s scientific
advisory committee said the standards should be tightened even more.

Many American manufacturing companies are trying to break into the Chinese market.
With about a billion people, the idea of selling goods in China is an attractive one, but
the GLRC’s Christina Shockley has the story of one company that’s having a hard time reaching
Chinese citizens. That’s because local environment and safety regulations often stand in the way:
Motorcycle maker Harley-Davidson opened a dealership in Beijing in April. It’s the
company’s first shop in China in at least 60 years.
Robert Kennedy is Executive Director of the William Davidson Institute at the University
of Michigan. The institute studies business and policy issues in emerging markets.
Kennedy says there’s a huge demand in countries like China for products associated with
the American way of life. He says Harley-Davidson motorcycles are a prime example:
“I mean, they’re associated with a particular lifestyle here, it’s a very American thing.
And they have very low penetration in China and India, and these other countries now,
but because there’s slowed demand growth in the US, if they want to grow, that’s a great
place for them to go.”
Kennedy says it’s very common for companies to try to ease restrictions in other
countries to make it easier for them to export goods and there are several restrictions on
motorcycles in China. The rules vary from community to community, but most large
cities ban, or severely limit, motorcycle use in the city center.
Experts say the rules are in place partly because of safety and environmental issues.
Barrett McCormick specializes in Chinese politics at Marquette University. He says
environmental problems can be intensified because Chinese roads are clogged, and most
motorcycles there are dirty:
“Anyone who’s been to China 10 years ago or something, a common site is some horrible
little motorcycle putting down the road, with a big cloud of smoke behind it, and I think that’s
the kind of thing that the Chinese government has regulated to eliminate.”
McCormick says air quality is one of China’s most pressing problems. A recent report
from the World Health Organization says many of the most polluted cities in the world
are in China. It says one of the main sources of air pollution there is motor vehicles
emissions.
Zhixin Wu is with a company that’s working with government agencies to develop
Chinese transportation policies. He says emissions from dirty, small motorcycles in
china account for roughly 50 or 60 percent of emissions in urban areas:
“In China almost all the motorcycles use the two stroke internal combustion engine.”
Wu says that type of small engine is very dirty. But, Harley-Davidson says those bikes
are a far cry from the motorcycles it produces:
“The motorcycles in use in China, I guess I wouldn’t even characterize them as
motorcycles. I would call them two-wheelers.”
Tim Hoelter is the company’s Vice President for International Affairs. He says Harley
bikes easily meet environmental regulations in every market in which they’re sold. And
Hoelter says the company is working with officials in the United States and China to get
this point across:
“Not too long ago the Chinese ambassador to the United States came to Milwaukee and
met with local business people. I sat two seats away from him at dinner, and was able to
talk to him about these riding bans.”
Hoelter says the company is also meeting with American trade officials, and authorities
in the Chinese government, to get the rules changed. He says his company has already
helped ease motorcycle restrictions in other countries, such as Vietnam and India.
Robert Kennedy, from the William Davidson Institute, says Harley-Davidson will
probably be able to get the rules changed in a few years, assuming the regulations have
the inadvertent affect of keeping out Harley motorcycles. He says China has a huge trade
surplus with the United States, and that’s a sensitive political issue.
Kennedy says it’s not unusual for countries to have rules that keep foreign goods out,
even if that’s not their intent:
“The US has some of these regulations that keep out other countries products, and other
countries have regulations that keep out our products. It’s not like under the Romans or
the British where a country would send in the army and force them to buy our goods, it’s
just governments working together to sort out the details to allow trade to happen.
Kennedy says even though most Chinese wouldn’t be able to afford Harley motorcycles,
there are many who could, and as people there become more wealthy, the possibility
exists for a huge market.

Officials at the Environmental Protection Agency are considering a new policy for sewage treatment plants. Many environmentalists say if the policy is adopted, it will lead to increased water pollution and greater risk to public health. The Great Lakes Radio Consortium’s Mark Brush reports on the debate over sewage blending:
(sound of water in sewer)
Some sanitary sewers are tied in with storm sewers. So when there’s a big rainstorm, or when there’s a fast snowmelt, all that water can inundate some sewage treatment plants. To tackle this problem, some treatment plants have adopted a practice known as “blending.” The excess sewage is re-routed around the slower parts of the treatment plant. The dirty water is then mixed with the water that’s been cleaned. It’s sometimes given a shot of chlorine, and then released into creeks, rivers, and lakes.
Kurt Heise oversees the operation of a sewage treatment plant on the Detroit River. He says the practice of blending is necessary in order to keep the plant from being overwhelmed.
“When you have a wet weather event, an extreme wet weather event, if we were to allow all of that combined water in through the normal process the treatment process would be ruined.”
Sewage blending has been around for a long time. To plant operators, it’s a necessary step in handling large amounts of dirty water. But to some people, blending is not seen as a good option. They want the practice to stop.
Instead, they say, cities should invest in their systems to make sure they can fully treat all the water that comes to the plant. Kurt Heise says, if his plant were required to do this, it wouldn’t make sense economically.
“It would almost result in doubling the size of our plant and spending just untold amounts of dollars for an event only happens a few times a year.”
Sewage treatment plant operators say you have to weigh the costs and the benefits before spending hundreds of millions of dollars on expanding the treatment plants. The decision of whether or not to allow blending has been left up to state and local regulators. But recently, the U.S. Environmental Protection Agency has weighed in on the subject. And ever since they suggested new guidelines for allowing blending, environmentalists have been critical of their plan. Mike Shriberg is the Great Lakes advocate for the Public Interest Research Group. It’s an environmental consumer activist organization.
Shriberg says the draft blending policy, the way it’s written now, is too broad. And will allow the practice of blending to become routine.
“Our fear is that when you’ve got a treatment plant that uses blending, they’re never going to upgrade to full treatment sewage. And so if a treatment plant is allowed to blend they’re not going to go up to full treatment capacity they have no incentive to do that anymore. It’s sort of the cheap way out.”
Sewage treatment operators say blending is better than seeing the raw sewage overflow into waterways. And they say it’s better than spending large sums of money to fix a problem that only occurs a few times a year. But critics say the EPA doesn’t have a good handle on how often blending is used, and what kind of health risks are associated with the practice.
Some initial studies have been done on blended sewage and how it might affect public health. Joan Rose is a water microbiologist at Michigan State University. She’s written a report on the health risks associated with blended sewage.
“So what I found was that if people were actually swimming in the water and there was a discharge of a blended sewage upstream, that their risk of getting sick, actually getting sick with a virus or a parasite was about a hundred times greater – when there was a blended discharge as opposed to if the water was fully treated.”
Rose says some of these viruses, such as Hepatitis-A, are highly contagious. At this point, there are no good estimates on how many people get sick from blended sewage each year. It’s never been studied, so the impact of blending on public health is unclear. Ben Grumbles is the Assistant Administrator for water at the EPA. He says the EPA is considering the billions of dollars at stake in expanding the nation’s sewer treatment plants versus the risk to public health.
“What we’re trying to do is to clarify what’s legal and what isn’t legal and to recognize the economic realities that sewage teatment plants face across the country in terms of their infrastructure needs, but foremost and above all what leaves the facility has to meet Clean Water Act permit limits.”
But the Clean Water Act permit limits don’t measure all the viruses, bacteria, and parasites found in blended sewage. And so some environmentalists and scientists say meeting the limits doesn’t necessarily mean protecting public health. Grumbles says officials are still reviewing the tens of thousands of comments they received after releasing the draft blending policy.
He says he doesn’t know what the final rule will look like, or if they’ll issue a rule at all. One thing is likely, if the policy is finalized the way it’s written now, it’s expected that environmental groups will take the EPA to court.
